SAMUEL K. EPLER, OF SAN DIEGO, CALIFORNIA.

PUMP.

Application filed June 7, 1913.

To all whom it may concern:

Be it known that I, SAMUEL K. EPLER, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented certain new and useful Improvements in Pumps,of which the following is a specification.

My invention relates to pumps.

Among the objects of the invention are: first the provision of aneffective form of manually operated pump which will produce acontinuous, even, and steady flow of the fluid pumped from aconsiderable depth; second to provide in a pump of this kind a pluralityof fluid lifting elements and cooperating parts which will serve toprovide a continuous suction so that a continuous flow of the fluid maybe had; third, the provision in a pump of this kind of a plurality offluid lifting elements adapted to alternately produce a suction andremain inactive for this purpose, one of said elements producing asuction while the other remains inactive for this purpose; and fourth,the provision in a pump of this kind when said lifting elements are inthe nature of heads of a valve device such as hereinafter set forth,which enables the heads to function as above stated.

The invention resides in the novel arrangement and combination of theseveral elements or parts described hereinafter in connection with theaccompanying drawings illustrating the preferred embodiment.

In said drawings: Figure 1 is a side elevation; Fig. 2 is a verticalsectional view; Fig. 8 is a vertical sectional view of the suction tube;and Fig. 4 is a detail perspective view of the suction operating valveemployed.

Throughout the views of the drawings, like reference charactersdesignate like or similar parts.

Referring specifically to the drawings, 1 designates a discharge chamberhaving a discharge outlet 1 the chamber being shown in the form of avertically disposed tube. The tube is fastened to, but out ofcommunication with, a horizontally arranged cylinder designated 2, anddepending therefrom is a suction tube 3, (see Fig. comprising aplurality of sections designated 4 screwed together as at 5, thelowermost section being preferably provided with any suitable form oftrap as at 6.

munication therewith, are the vertically disposed suction cylinders 8having at their upper ends removable caps 9. The ends of the cylinder 2are projected slightly beyond the cylinders 8 and there receiveremovable closure caps 10. Said chamber 1 and tubes 8 communicatethrough the medium of connecting tubes 8. Chamber 1, cylinders 2 and 8and one section of the suction tube 3 are preferably formed as anintegral part of said integral structure, and has therein a suitablevent valve as at 11. A cross-head 12 is provided to be mounted adjacentthe upper end of the cylinder and packing nuts 13 are adapted to screwonto the stuffing boxes 14 provided around the rod having extensiblemovement into and from the several cylinders.

Extending through the cross head 12, chamber 1, cylinder 2, and into thesuction chamber, is a hollow rod designated 15 on which is suitablyfastened a suction head 16. \Vithin the tubular rod 15 is slidablymounted a rod 17, the end of which extends somewhat below the end of rod15 and has provided thereon a suction head 18. The suction head 16 maybe of any suitable construction as to draw up the water on the up strokeand to permit the passage of water therethrough or past the same on thedown stroke. As shown in the drawings, the suction heads 16 and 18 aremade of suitable flexible material such as leather, so that their outerwall will yield inwardly on the down stroke to permit the upward passageof water between the head and wall of the tube bore. At the upper end ofthe rod 17 is fastened a cross piece 19 as by means of a set screw 20,which cross member is likewise fastened by a set screw 21 to a rod 22.To the lower end of the rod 22 and t0 the upper end of the tubular rod15, are fastened cross arms 23 as by means of set screws 24 engaging theproper rods 15 and 22. On each cross arm 23 is fastened as at 25, rods26 which extend and slide through the cross head 12, stufling box let,caps 9, and thence into the pump cylinders 8,.being provided at theirends with suitable upper suction heads 27, as are the suction heads 16and 18, the suction heads 27 are constructed to draw up or elevate thewater on the up stroke and permit the passage of the water therethrough,or past the same on the down stroke. To this end said heads 27 arepreferably made of flexible material, such as lOQ leather, so as toyield similarly to the. heads 16 and 18. It might be here stated thatthe tubular rod 15 extends through the cross head 12, the centralextension thereon, and the stufling box 14 of the discharge cham ber 1.Thus it will be realized that the eX- tensions, glands, and packing formsuitable packing or stufiing boxes for the piston rods 26 and tubularrod 15.

In the cylinder 2 is mounted for lateral movement, a valve deviceadapted at times to cut off communication between tube 3 and cylinders8, having at opposite ends, heads 28 being fastened together by means ofa connecting member 29, being formed intermediate its ends to provide anelongated slot 30 through which the rods 15 and 17 pass, asbest seen inFig. 2. I Within the chamber 2 is preferably provided, interior-1yextending annular flanges 31 which form abutments to limit the slidingmovement of the heads 28.

Fastened to the cross head 12 are the arms 32 of an inverted V-shapedbracket to which is pivoted at its upper end on a pivot member 33, anoperating lever or handle designated 34. The lever 34: has adjustablyfastened thereto, clamp blocks 35 as by means of the set screws 36, towhich blocks are pivoted at 37, pitman rods 38 also pivoted as at 39 tothe cross arms 23.

In operation, the operating lever 31 is rocked or moved verticallythrough manual engagement, which action causes the alternate raising andlowering of the suction heads 27 and suction heads 16 and 18, it beingclear that the pitman 38 of one cross bar 23, effects the movement ofthe rod 17 through its connection thereto by means of the'rod 22 andconnecting member 19. The other pitman 38 by means of the other crossarm 23, causes the shifting of thetubular rod 15 and suction head 16carried thereby, and which latter arm 23 also causes movement of theother piston 27 through its connection thereto by means of its rod 26.one set of connected upper and lower suction heads move simultaneouslyupwardly, the other set of connected upper and lower suction heads movesimultaneously downwardly, the flexible construction of the heads 16 and18 and 27 permitting the water to act against the same and contract themso that the water may gush or flow upwardly around the same. Thus whileone set of upper suction heads and lower suction heads is on the upstroke creating a suctiion, through the pump and lifting the water, the

other set of upper suction heads and lower suction heads are on theirdown stroke. This action is alternate. By means of this arrangementthere is always a suction in the pump which causes a continuous and evenflow of water to pass through tube 3, cylinders 2 and 8, tubes 8,chamber 1, and

from the same through the opening at I When one of the'heads 27 movesupwardly on its up stroke and creates a suction through the pump, thevalve device having the heads 28, is shifted longitudinally so that thehead 28 adjacent the other cylinder, will cut ofi all communicationtherewith. Upon the down stroke of this same upper suction head theother upper suction head will start to move upwardly which will thusdraw the adjacent head 28 away from its seat or flange 31, to permit theproper suction through the pump. l/Vhile the heads 27 descend, the valveheads 28 are in such position as to close communication between theproper chambers 8 and tube 3, whereby the water pumped into the tubes 8is prevented from back-flow into tube 3, Likewise the construction ofthe heads 17 and 18 prevent the return of backfiow of the waterafter'being pumped past the same into tube 3.
